摘要

健康的足月妊娠母亲在产后第 1 天到第 30 天的母乳中,MMP-2 和 TIMP-4 的表达存在时间差异:(i) MMP-2 活性在第 1 天(初乳)达到峰值,之后呈指数下降;(ii) TIMP-4 的表达在第 7 天达到最高值,之后持续存在。根据我们的初步研究结果,人乳中 MMP 和组织抑制剂的不同表达可能与人乳的保护作用有关。

Differential expression of matrix metalloproteinases and the tissue inhibitor in human milk.

There are differences in the temporal expression of MMP-2 and TIMP-4 in human milk from Day 1 to 30 postpartum in healthy mothers of term pregnancies: (i) MMP-2 activity peaked at Day 1 (colostrum) then exponentially decreased afterwards; and (ii) The expression of TIMP-4 was maximal at Day 7 and persisted thereafter. From our preliminary findings, the differential expression of MMP and the tissue inhibitor in human milk may be related to the protective action of human milk.
